You may or may not be aware that a lot of modern HDTVs have firmware, which can be updated allowing the set to be upgraded to the very latest version. Many HDTVs have a small USB port which can be used to apply the firmware update (via USB memory stick) as well as form playing back photos and other media.
The firmware is what runs in the “brains” of your HDTV set, and over time bugs can be found or new features are added to the set, you should always check to see if you there are updates available on the internet to ensure you are running the latest and best version of the firmware for your TV.
